| Research Abstract |
Charge-exchange (p,n) reaction to isobaric analog state has been investigated for the purpose of developing a new approach to the measurement of neutron-skin thickness. This reaction is equivalent to the proton elastic scattering under the isospin symmetry, and the slope of its differential cross section is expected to be determined by the root-mean-square radius of the isovector component of the density distribution. The differential cross sections of the (p,n) IAS reaction from 116Sn and 120Sn have been measured and compared as functions of the momentum transfer. It was found that the slope of120Sn is steeper than that of 116Sn by 4%, which is expected to be the consequence of the fact that120Sn has a thicker neutron skin than 116Sn
